TIRE Fort AU'iioivio'BIniisQ f To all whom ii /nay concern 'silient tread yieldable to the extent ofrelieving the vehicle of jolts and jars in passmg over. uneven 'surtaces, and promoting tractionfby .afi ording an effective grip on the roadway. The conventionaltype of tire of this general character is constructed of an outer casing or shoe composed principally of .rubber'and attached to the rim of the wheel in a suitable manner, in connection with a continuous rubber tube inc'losed within the shoe or casing and inflated sufficiently to insure the tire-structure properly sustaining the load of the vehicle and giving the required resiliency, commonly known as a pneumatic tire. However, a tire, of this na ture though generally practical isdependent for constant successful'operation on the perfeet or unimpaired condition of the inner tube, and as the latter isliable to be punctured when the shoe'or casing is pierced by any object the life or utility of such a tirestructure is uncertain.

It is the purpose of my invention, therefore, to provide a vehicle-tire possessing all the advantages of the ordinary pneumatic tire with the additional and important advantage of not being liable to deflation or collapse by puncture, and this purpose I attain in the present instanceby certain mechanical means herein shown described, and specifically claimed.

In the accompanying drawings, which:

form a part hereof-Figure l is a fragmentary view of a wheel provided with a tire constructed in accordancewith my present invention, a part of the casing or shoe being broken away to show the internal construction. Fig. 2 is a transverse sectional view throughthe tire. Fig. 3 is a side view of the means employed for maintaining the Specification of Letters iatent. f J- Patented Feb 15 -1916 Application filed.

wheehbyEcontraCting rings 12, these parts being ofjthe usualland .ordi'lnary construc tion, and therefore'other means for attache ing the casing 'orshoe'to therimmay be" employed. I

1n carrying out my invention the outer casing or shoe is provided with a fiat metal ring 15, fitting: within said casing at the outer or tread portion thereof, and therefore terferingwith the other parts,hereinafter referred to, said end is beveled, as shown in Fig. 5, and'i'n practice may be welded to the-other portion of said joint. Furthermore, the metal strip is curved at either side of its center, as at 15, 15, for the purpose hereinafter explained. v

In connection with the metal strip 'or shield just described'I employ-'a'm'ediurn for yieldably 'distending-l the tire comprisingv a ring 16,, round in cross-section and of ap proximately the same diameter as the internal diameter of the casing or shoe l0, withinv which it is adapted tonsnn'gly fit. Infthis instancesaid ring is in the "form .of a con-y tinuous helical spring, and is made of flat steel wire with the helices or convolutions spaced-aslight distance apart, the gage "(if the flat wire depending upon the size of the tire and load it is intended thewheel shall support. In using this yieldable casing supporting ring the protecting metal shield 15 is interposed betweenit and'the tread per tion of the casing or shoe, as illustratedin Fig. 1 of the drawings, to assist in reinforc ing the same or increasing its stability, as Y 'well as to reduce the. wear betweenthe ring i andthe shoe or casing;

It'will' be apparentithat theinwardly reinforcing. portions :therebeyond; whereby said bridge portion .will yield readily under ordinary conditions in the running of the 7 wheel, and the reinforcing portions take up the strainof an extraordinary load or when the. tire strikes anzohstruction and, second-,1

the inwardly-curved portions form reduced bearing surfaces resting-against the helical spring ;to co-act therewithl inproviding a greater amount of resiliency.

In order to prevent the convolutions of ing medium consistingof a hemp ropell'T consisting of several strands twisted. to: gether, as indicatedz -in -Fig; 2,. and-entirely fillingsaid ring,'whereby' it willi 'not only effectually prevent the convolutionslapping as the tire structure. yields in the joperation parts .in carrying the load supported :by the 3O wheel.

15; these partscotiperating to forma structure that will yield to a. certain extent; as the wheeL passes over the ground and thus beingfresilient will'readily take up any jars or jolts incident to thevehicle passi'ngover uneven surfaces-. It will be noted,' also, that the parts relied upon to properly distencl thecasing or shoe are possessed of suilicient strength to withstand the Work ;to'fwhich such .a wheel is ordinarily subjected.

f In; some instances, vI contemplate using 7 the metal shield 15 in connectionawithia rubbertube,.or What iscommonly known as an inner-tube,- 185' shown in the modification.

Fig. 6 of the drawings; and in this instance the protectingshield not only acts to reinthe important purpose of protecting theinof the tire is increased by=the fact that; the
